Romania’s National Power System (SEN) has surpassed the 2,500 MW threshold of new electricity generation and storage capacity connected to the grid since the beginning of 2026, Transelectrica announced.
The milestone was reached with the grid connection of a new energy storage facility, IS Părău, with a capacity of 76.76 MW / 150.288 MWh.
The newly connected capacities are linked both to the Transmission Electricity Network (RET) and to electricity distribution networks and are at different stages of development, ranging from facilities that already hold commercial operation licenses to installations undergoing internal functional tests and compliance testing.
The breakdown by resource type of the 2,514 MW of capacity installed in 2026 is as follows:
- Hydrocarbons: 20 MW
- Wind: 496 MW
- Energy storage: 663 MW
- Photovoltaic: 1,331 MW
- Biogas: 5 MW
The capacities that have pushed the total above 2,500 MW include both new power generation plants and energy storage facilities, contributing to the diversification of Romania’s energy mix and increasing the resources available for the operation of the National Power System.
According to Transelectrica’s estimates, the process of connecting new capacities to the SEN will continue at a sustained pace in the coming period, with the involvement and support of experts from Transelectrica and electricity distribution system operators. Their work covers all stages, from preparing the grid connection process to connection to the SEN and the commissioning of the facilities.
By the end of 2026, Transelectrica estimates that approximately 1,000 MW of new solar and wind generation capacity and around 1,000 MW of new energy storage capacity will be connected to the grid. These additions will be complemented by new natural gas-fired generation capacity from the Mintia and Iernut power plants.
